Pros
Pro Excellent screen uniformity
The AOC U2879VF has excellent screen uniformity, both in terms of luminance and color. In fact, this panel scores extremely well with a luminance deviation of 6.32 percent - which is better than most displays with IPS panels. No backlight bleeding or hotspots are present.
Pro Fast response time, great for gaming
With a response time of just 1ms, the AOC U2879VF is one of the fastest monitors on the market. Ideal for fast-paced gaming situations such as first person shooters.
Pro Thin bezel makes it ideal for multi-screen setups
The bezel of this display measures a thin 17 mm, which doesn't only result in a smaller build, but it makes the U2879VF also more suitable for multi-display setups.
Pro Support for MHL allows you to quickly connect a media device
This monitor supports MHL - short for Mobile High-Definition Link - which allows you to connect an Android smartphone or tablet to the U2879VF monitor.
Pro Excellent grayscales in sRGB preset, great for graphical work
When using the sRGB preset - which is particularly useful for graphical editing - the grayscale error readings of the U2879VF are quite low for a relatively inexpensive panel. The error measures was 0.93 Delta E - that's only a tad worse than specific graphical displays which retail for a much larger price. For comparison, a standard 28" TN panel measures at 1.60 Delta E. (Lower is better.)
Pro Extremely sharp
The AOC U2879VF uses a 4K-display with a resolution of 2160 x 3840 pixels, which is four times the amount of pixels of a Full HD display. This results in an extremely sharp image and overall great image quality. In terms of pixel density (measured in pixels per inch), this display measures at 163 ppi. For comparison - a Full HD display of the same size will only achieve half of that - 81.5 pixels per inch.
Pro Great value for the money
The AOC U2879VF is a cheap Ultra HD display with good image quality, the price/quality ratio of this display is quite high.
Pro Supports daisy chaining
The Dell U2415 is an excellent solution for those who use display daisy chaining since it has a dedicated DisplayPort Out.
Pro Has a USB hub
The monitor’s integrated USB hub consists of four downstream USB 3.0 ports that you can use to charge peripheral USB devices or connect them to your computer. The single upstream port offers high data transfer rate typical of USB 3.0.
Pro Looks good
While other gaming monitors tend to look overly aggressive, the Dell U2415 looks somewhat professional because of its clean and simple design that allows the monitor to blend in almost any working environment.
Pro No signs of image retention
The Dell U2415 was tested to be free of image burn-in problems that are common among monitors in this price range.
Pro Can be used in portrait mode
The Dell U2415 does an excellent job even when used in portrait mode because of its superb vertical viewing angles that are superior to what the overwhelming majority of competitors in this price range offer. When used in portrait mode, the monitor’s colors and shadows start to shift only when the viewing angle becomes greater than 25 degrees.
Pro Adjustable
Setting the monitor according to your workspace needs is simple because the stand supports all the key ergonomic adjustments, including height, tilt, pivot, and swivel.
Additionally, you can mount the Dell U2415 on a VESA 100x100 compliant monitor stand.
Pro Factory calibrated
Out of the box, the Dell U2415 displays 99% of the sRGB colors, which is an extremely rare feature for a monitor in this price range.
Pro Flicker-free
The Dell U2415 doesn’t put additional strain on your eyes since its backlight doesn’t flicker. Monitor flickering can cause severe eye fatigue over extensive use.
Pro Good for occasional gaming
The Dell U2415 is an excellent companion for those enjoying a casual round of CS: GO or LOL in between working hours because the monitor offers reasonably high responsiveness and well-handled motion.
It's works good even while playing fast FPS games as the monitor’s input lag of 9.1 ms is barely noticeable by most players.
Furthermore, the Dell U2415 makes motion appear free from artificial motion blur thanks to its full pixel response time of 6 milliseconds which allows each pixel of the Dell U2415 to change their color within only six milliseconds.
Pro Good for bright rooms
The Dell U2415 does a great job in bright rooms, where its 275 nits of peak brightness and light matte screen finish diffuse reflections and fights glare efficiently.
Pro Suitable for professional photo editing
The Dell U2415 is an excellent tool for the photography professionals who work in the sRGB color space. Not only does it support the entire palette of sRGB colors, it also can display those colors with high accuracy since it’s average color error dE is measured at only 0.45. Even the highest-class media professionals will not be capable of perceiving such minor color error.
Pro Decent picture quality
The Dell U2415 is among the best monitors in the sub-$200 range since its native contrast ratio, peak brightness, gamma and color accuracy are on par with what the best monitors in this price range offer.
It displays beautiful images with rich and well-balanced blacks, accurate colors, and realistic intermediate tones that gives the picture some extra intensity. Dark scenes look deep as the monitor’s high-quality IPS panel offers a native contrast ratio of 1064:1, which combined with the monitor's overall color uniformity gives its blacks a good push towards high-intensity levels. Colors pop and look beautiful thanks to the monitor’s high peak brightness of 275 nits, which combined with the panel’s low average color inaccuracy allows the Dell U2415 to display crisp and life-like colors. The monitor’s mid-tones look realistic as its gamma response is only 1% away from its perfect value.
Moreover, the monitor’s average color inaccuracy dE of 0.45 ensures that only professional photosensors can spot its color inconsistencies as those are very minor.
Pro Good for mixed-use
The Dell U2415 offers exceptional color accuracy, high adjustability, decent responsiveness, and high resolution which, combined with its good overall picture quality makes it one of the best monitors in this price range.
Pro Higher resolution than FHD
The Dell U2415 has 11% more pixels than a regular FHD monitor which will come in handy when working with large, high-resolution photos.
Cons
Con Disappointing input lag
The absolute input lag measured on this display is quite high at 87 ms. Although this won't disturb casual players, it's definitely not ideal for fast-paced gaming situations - despite a fast response time.
Con Maximum refresh rate limited to 75 Hz, less ideal for fast-paced action
The maximum supported refresh rate of this monitor is 75 Hz or 75 frames per second which is a tad faster than non-Freesync monitors, but is not as good as 120 or 144 Hz displays. Especially fast-paced games benefit from a higher refresh rate, for a more fluid gaming experience.
Con 4K resolution doesn't scale well with all software
Due to the native 4K resolution and the relatively small 28 inch screen size, text can be hard to read in Windows and other non-gaming environments, such as Adobe's software. Not everything scales well in 4K (yet).
Con Red is slightly under-saturated
The display suffers from a slight under-saturation of the red color, which is a caveat for some graphical applications. This also can't be fixed through software, it's a hardware limitation of the panel.
Con Doesn't offer support for VESA mounts
The design of this display is proprietary and there is no support for the universal VESA standard. As a result, wall-mounting this display isn't possible, and alternative stands aren't compatible as well.
Con Requires calibration
To get the most out of the monitor’s performance, you need to calibrate it. The procedure will take you 5-10 minutes as the monitor’s optimized ICC profile is available on the Internet.
Con Lacks speakers
Not a huge dealbreaker, but it's something to consider.
Con Not suitable for Adobe RGB content
This monitor is not the right tool for those who work with Adobe RGB as it supports only 70% of the Adobe RGB colors.
Con Doesn’t look good in a dark room
In a dark room, you can notice some minor backlight bleeding that occurs towards the lower part of the screen. Backlight bleeding appears when the panel can’t absorb the 100% of the monitor’s backlight and limits the monitor’s use in a dark environment.
However, this is a widespread issue for the IPS panels in this price range.
